Application filed March 14, 1916. Serial No. 84,102.

To all whom it may concern:

Be it known that I, WILLIAM L. Barnes, a citizen of the United States, residing at McMinnville, in the county of Warren and State of Tennessee, have invented certain new and useful Improvements in Nheel- Guards and Track-Cleaners for Saw-Carriages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The primary object of this invention is to improve the general construction of combined wheel guard and track cleaner for saw carriages by admitting of the track cleaning members having both vertical and horizontal adjustments with respect to the guard.

Another object of the invention is to provide a novel type of track cleaning device which will have a large track engaging surface and which when in operative position will be in close relation to the wheel of the saw carriage.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a side elevation of the track cleaner, Fig. 2 is a top plan view thereof, Fig. 3 is a vertical section taken through one of the cleaning members, and Fig. 4. is a perspective view of one of the track cleaning members detached from the wheel guard.

Referring to the drawings more in detail the numeral 1 designates one of the wheels of the saw carriage adapted to travel on the track 2.

The combined wheel guard and track cleaner consists of a pair of horizontally disposed elongated plates 3 arranged re spectively, on opposite sides of the wheel 1, and each has its upper longitudinal edge cut away in an inwardly curved plane, as shown at and has its lower longitudinal edge cutaway as shown at 5 to provide a recess, the opposite end walls of which diverge downwardly as shown at 6. By vir- 3 as shown more clearly in Fig. 1 of the drawings. Each of the cleaning blocks 8 is wedge shaped and has its lower or enlarged end thereof slidably engaging the track 2. 'ihe blocks 8 have transverse openings 9 extending therethrough, and each block being provided with a pair of such openings arranged one above the other and which receive bolts which pass through the heads 7 and through the openings 9 and each have one end threaded for the reception of a nut 11 which is adjustable against the adjacent head 7, as shown in Fig. 3 of the drawings. The diameters of the openings 9 are considerably greater than the diameters of the bolts 10, so as to admit of the cleaning blocks 8 having both vertical and horizontal adjustments with respect to the plates 3, so as to compensate for the wear of the block. By adjusting the nuts 11 against the adjacent heads 7, opposing heads will tightly clamp therebetween the adjacent block and hold the same in adjusted position. The cleaning blocks 8 are to be made of hard wood, so as to prevent wear of the tracks 2 and the peripheries of the wheels 1. By virtue of forming the blocks 8 wedge shaped,

each block can be reversed, when the space I adjacent the wheel becomes worn, and the opposed face of the block presented to the periphery of the wheel.

What is claimed is:

1. A device of the class described comprising a pair of horizontally disposed spaced plates, track cleaning elements mounted between the plates and adapted to have vertical and horizontal adjustments with respect to the plates, and means for holding the elements in adjusted position.

2. A track cleaner comprising spaced side plates, wedge shaped blocks reversibly positioned between the plates and fastening elements extending through the plates and the blocks.

3. A device of the class described comprising a pair of plates, and track cleaning ele- In testimony whereof I aflix my signature 1n presence of two witnesses.
